最終效果

首先來看看效果圖：

其他地方很好實現，就是熱門搜尋有點麻煩，由於資料的不確定性，那麼像GridView明顯不能滿足了，這時候就只能自己來定義一個佈局了。

最終實現後的效果：

具體實現

1，自定義一個類繼承ViewGroup

public class ZFlowLayout extends ViewGroup{

    // 儲存所有子View
    private List<List<View>> mAllChildViews = new ArrayList<>();
    // 每一行的高度
 

    private List<Integer> mLineHeight = new ArrayList<>();
    public ZFlowLayout(Context context) {
        this(context, null);
    }

    public ZFlowLayout(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public ZFlowLayout(Context context, AttributeSet attrs, int
 
 defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // 父控制元件傳進來的寬度和高度以及對應的測量模式
        int sizeWidth = MeasureSpec.getSize(widthMeasureSpec);
        int modeWidth = MeasureSpec.getMode(widthMeasureSpec);
        int
 
 sizeHeight = MeasureSpec.getSize(heightMeasureSpec);
        int modeHeight = MeasureSpec.getMode(heightMeasureSpec);

        // 如果當前ViewGroup的寬高為wrap_content的情況
        int width = 0;// 自己測量的 寬度
        int height = 0;// 自己測量的高度
        // 記錄每一行的寬度和高度
        int lineWidth = 0;
        int lineHeight = 0;

        // 獲取子view的個數
        int childCount = getChildCount();
        for(int i = 0;i < childCount; i++){

            // 測量子View的寬和高
            measureChild(child, widthMeasureSpec, heightMeasureSpec);
            // 得到LayoutParams
            MarginLayoutParams lp = (MarginLayoutParams) getLayoutParams();
            // 子View佔據的寬度
            int childWidth = child.getMeasuredWidth() + lp.leftMargin + lp.rightMargin;
            // 子View佔據的高度

            // 換行時候
            if(lineWidth + childWidth > sizeWidth){
                // 對比得到最大的寬度
                width = Math.max(width, lineWidth);
                // 重置lineWidth
                lineWidth = childWidth;
                // 記錄行高
                height += lineHeight;
                lineHeight = childHeight;
            }else{// 不換行情況
                // 疊加行寬
                lineWidth += childWidth;
                // 得到最大行高
                lineHeight = Math.max(lineHeight, childHeight);
            }
            // 處理最後一個子View的情況
            if(i == childCount -1){
                width = Math.max(width, lineWidth);
                height += lineHeight;
            }
        }
        // wrap_content
        setMeasuredDimension(modeWidth == MeasureSpec.EXACTLY ? sizeWidth : width,
                modeHeight == MeasureSpec.EXACTLY ? sizeHeight : height);
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        mAllChildViews.clear();
        mLineHeight.clear();
        // 獲取當前ViewGroup的寬度
        int width = getWidth();

        int lineWidth = 0;
        int lineHeight = 0;
        // 記錄當前行的view
        List<View> lineViews = new ArrayList<View>();
        int childCount = getChildCount();
        for(int i = 0;i < childCount; i ++){
            View child = getChildAt(i);
            MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();
            int childWidth = child.getMeasuredWidth();
            int childHeight = child.getMeasuredHeight();

            // 如果需要換行
            if(childWidth + lineWidth + lp.leftMargin + lp.rightMargin > width){
                // 記錄LineHeight
                mLineHeight.add(lineHeight);
                // 記錄當前行的Views
                mAllChildViews.add(lineViews);
                // 重置行的寬高
                lineWidth = 0;
                lineHeight = childHeight + lp.topMargin + lp.bottomMargin;
                // 重置view的集合
                lineViews = new ArrayList();
            }
            lineWidth += childWidth + lp.leftMargin + lp.rightMargin;
            lineHeight = Math.max(lineHeight, childHeight + lp.topMargin + lp.bottomMargin);
            lineViews.add(child);
        }
        // 處理最後一行
        mLineHeight.add(lineHeight);
        mAllChildViews.add(lineViews);

        // 設定子View的位置
        int left = 0;
        int top = 0;
        // 獲取行數
        int lineCount = mAllChildViews.size();
        for(int i = 0; i < lineCount; i ++){
            // 當前行的views和高度
            lineViews = mAllChildViews.get(i);
            lineHeight = mLineHeight.get(i);
            for(int j = 0; j < lineViews.size(); j ++){
                View child = lineViews.get(j);
                // 判斷是否顯示
                if(child.getVisibility() == View.GONE){
                    continue;
                }
                MarginLayoutParams lp = (MarginLayoutParams) child.getLayoutParams();
                int cLeft = left + lp.leftMargin;
                int cTop = top + lp.topMargin;
                int cRight = cLeft + child.getMeasuredWidth();
                int cBottom = cTop + child.getMeasuredHeight();
                // 進行子View進行佈局
                child.layout(cLeft, cTop, cRight, cBottom);
                left += child.getMeasuredWidth() + lp.leftMargin + lp.rightMargin;
            }
            left = 0;
            top += lineHeight;
        }

    }

    /**
     * 與當前ViewGroup對應的LayoutParams
     */
    @Override
    public LayoutParams generateLayoutParams(AttributeSet attrs) {
        return new MarginLayoutParams(getContext(), attrs);
    }
}

2，佈局引入自定義View

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.hkddy8.flowlabledemo.MainActivity" >
    <com.hkddy8.flowlabledemo.view.ZFlowLayout
        android:id="@+id/flowLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</RelativeLayout>  

3，使用

public class MainActivity extends Activity {
    private ZFlowLayout mFlowLayout;
    private String[] mLabels = {"購物","美食","遊玩","北京","CSDN", "Airsaid", "周遊", "新春送祝福"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mFlowLayout = (ZFlowLayout) findViewById(R.id.flowLayout);
        initLabel();
    }
    // 初始化標籤
    private void initLabel() {
        MarginLayoutParams layoutParams = new MarginLayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        layoutParams.setMargins(30, 30, 10, 10);// 設定邊距
        for (int i = 0; i < mLabels.length; i++) {
            final TextView textView = new TextView(MainActivity.this);
            textView.setTag(i);
            textView.setTextSize(15);
            textView.setText(mLabels[i]);
            textView.setPadding(24, 11, 24, 11);
            textView.setTextColor(Color.BLACK);
            textView.setBackgroundResource(R.drawable.lable_item_bg_normal);
            mFlowLayout.addView(textView, layoutParams);
            // 標籤點選事件
            textView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(getApplicationContext(), mLabels[(int) textView.getTag()], Toast.LENGTH_SHORT).show();
                }
            });
        }
    }
}

其中背景的Shape程式碼：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <stroke
        android:width="1dp"
        android:color="#000000" />
</shape>
